Definitions

  • the present invention relates to an injection molding device for the production of multi component injection molded products.
  • US2010117440A was first published in 2009 in the name of Zahoransky A G. It describes a brush manufacturing machine which has a first injection-molding machine for the region-by-region injection molding of material around bristle bundles held in cartridges and for forming a bristle carrier connecting the bristle bundles.
  • a second injection-molding machine is present in which the bristle carrier can be inserted and material can be injection molded around this carrier for forming a brush body or partial brush body.
  • the first injection-molding machine is constructed for forming a thin-walled plate as a bristle carrier and has a shorter cycle time than the second injection-molding machine.
  • At least the second injection-molding machine is constructed as a multi-compartment injection-molding machine and has a multiple of the number of mold cavities of the first injection-molding machine.
  • US2001013152 was first published in 2000 in the name of M and C Schiffer GmbH. It relates to a method of manufacturing a brush head comprising a brush head body carrying bristle bundles, such as tooth brushes, by way of injection molding.
  • a first plastic component is injected into a first mold cavity for forming a bristle carrier.
  • the ends of the bristle filaments projecting into the first mold cavity are encompassed by the first plastic component.
  • the bristle carrier manufactured during the first step is relocated into another mold cavity, which is larger than the bristle carrier, and which is filled with a hard component.
  • a brush head complying with the above-mentioned demands, that the brush body comprises a bristle carrier encompassing the bristle filaments on the attachment side, said bristle carrier being embedded into a hard component.
  • the injection molding devices known from the prior art are relatively complex and slow. It is an object of the invention to provide a more efficient and precise device for the making of multi component injection molded products.
  • the invention is therefore directed to injection molding devices for the efficient production of complex multi component injection molded products, such as e.g. blood bags, beverages bags for drinks or other liquids and similar products comprising two or more components.
  • complex multi component injection molded products such as e.g. blood bags, beverages bags for drinks or other liquids and similar products comprising two or more components.
  • Products such as e.g. blood bags normally comprise a bag (first component), a spout (second component) and a seal (third component) which are interconnected to each other. While the spout is attached to the bag, the seal is normally made from a different material then the spout. In a preferred embodiment the seal is attached to a plug which is interconnected to the spout by a film hinge (thin stripe of material). The spout and the plug are preferably made from the same material (second component).
  • Products such as e.g. toothbrushes may comprise brushes (first component), a carrier for the brushes (second component) and a brush body (third component) which are interconnected to each other. While the carrier is attached to the brushes, the brush body is attached to the carrier.
  • Products such as e.g. golf balls normally comprise a core (first component), an inner layer (second component) and an outer layer (third component). While the inner layer encompasses the core, the outer layer encompasses the inner layer.

  • the at least one first cavity is at least partially arranged between a first side plate and a second side plate of a cavity module which is separable from the middle mold part.
  • the middle mold part comprises at least one recess foreseen to receive the at least one cavity module during production.
  • a number of the cavity modules can be arranged outside of the middle mold part.
  • the number of cavity modules can be higher than the number of recesses in the middle mold part.

  • At least one side plate of the cavity module is interconnected to the middle mold part while the second side plate is arranged movable with respect to the first side plate between an open and a closed position.
  • the second side plate is arranged rotatable about a hinge axis and/or in a translational manner with respect to the first side plate of the related cavity module.
  • a handling system can be interconnected to the injection mold to handle at least the first components and/or the final multi component injection molded products.
  • the handling system can be used to insert and/or remove the first component from the first cavity when the cavity is in an open position.
  • the handling system can comprise means to open and/or close the first cavity of the cavity module. Alternatively or in addition these means can be incorporated in the middle mold part.
  • the handling system interacts with a side face of the middle mold part arranged at an angle of 90° with respect to the side faces under production, i.e. those which are interacting with the outer mold parts for injection molding.
  • a third component which is interconnected to the second component can be made as follows: A first cavity half of a third cavity is arranged adjacent to the first cavity half of the second cavity and interacts in a closed position of the injection mold with a second cavity half of the third cavity arranged in the second outer mold part.
  • the third cavity is foreseen to receive a liquefied second plastic material to form the third component of the multi component injection molded product.
  • the third cavity can at least partially be integrated into the cavity module and/or the side face of the middle mold part in which the cavity module is arranged.
  • the first and/or the second mold half may comprise additional cutting means to trim the first component.
